EXPANDABLE BROADHEAD WITH PIVOT ARMS OR SLIDING ARM FOR RETRACTING AND EXPANDING ATTACHED CUTTING BLADES
First Claim
1. An arrow broadhead adapted for attaching to an open end of an arrow shaft insert in a hollow arrow shaft, the broadhead adapted for moving from a retracted position during arrow flight to an expanded position when contacting a target, the broadhead comprising:
- a housing body having a top portion, a middle portion, and a bottom portion, the top portion and the middle portion having an elongated groove and a shaft bore hole therethrough, the elongated groove having a groove bottom next to the bottom portion, the bottom portion having a threaded end extending downwardly therefrom, the threaded end adapted for attaching to the arrow shaft insert;
a removable, pointed blade tip received in an upper portion of the groove and attached to the top portion of the housing body;
a sliding arm received through the elongated groove and the bore hole;
a first cutting blade having an outside cutting edge and an inside edge with cam surface, one end of the first cutting blade pivotally attached to the sliding arm, a portion of the first cutting blade received inside the groove when the broadhead is in a retracted position; and
a second cutting blade having an outside cutting edge and an inside edge with cam surface, one end of the second cutting blade pivotally attached to the sliding arm, a portion of the second cutting blade received inside the groove when the broadhead is in a retracted position;
whereby, when the pointed blade tip and the first and second cutting blades contact the target, the sliding arm moves downwardly in the groove and the cam surface of the first and second cutting blades engage opposite ends of the groove bottom and the first and second cutting blades move outwardly into an expanded position for maximum cutting and target penetration.

Abstract
An arrow broadhead having a pair of cutting blades held in a retracted position during arrow flight and extending outwardly in an expanded position upon arrow contact. The subject broadhead includes a pair of pivot arms or sliding arm received in an elongated groove in a cutting blade housing body. The pivot arms or sliding arm are attached to one end of the cutting blades. At least a portion of the cutting blades are folded into the groove during arrow flight. Upon target contact, the pivot arms or sliding arm pivot the cutting blades outwardly from opposite sides of the groove into an expanded position for increased cutting and penetration in the target.
